Entities can be better described as “data elements Define your facts, measures, and dimensions. A fact is the part of your data that indicates a specific occurrence or While there are many ways to create data models, according to Len Silverston (1997) only two modeling methodologies stand out, top-down and bottom-up: Bottom-up models or View Integration models are often the result of a reengineering effort. They usually start with Top-down logical data models, Some data modeling methodologies can be thought of as database-centric, which means they are dedicated to graphical depictions of data and the relationships among data objects, with the eventual goal of designing and creating a database. I recommend that every data modeler be familiar with the techniques outlined by Kimball.

Data Modeling is a process of creating data models for the data to be stored in a database. It is a conceptual representation of Data objects, associations between different data objects, and the rules. Data modeling helps visualize data and enforces business rules, regulatory compliances, and government policies on the data.

I recommend that every data modeler be familiar with the techniques outlined by Kimball. Terms such as "facts," "dimensions," and "slowly changing dimensions" are critical vocabulary for any practitioner, and having a working knowledge of those techniques is a baseline requirement for a professional data modeler. Access is by value comparison: For value V: if V <= left value: → move to the left lower node if left value < V <= right value: → move to the middle lower node if V > right value: → move to the right lower node.
